Abstract

The invention belongs to the technical field of high-molecular materials, and especially relates to a preparation method for a polyolefin-kind high-molecular obstruction explosion-proof material. The method comprises fully drying polyolefin, a fire retardant, an antistatic agent, a flexibilizer and various auxiliary agents, uniformly mixing in a high-speed mixer, then adding into a screw-combined co-rotating conical twin-screw extruder with an appropriate length-diameter ratio, setting the extruder temperature to be 160-280 DEG C, performing cooling and heating processing, then sending into a slitting system, and cutting into an obstruction explosion-proof polyethylene material pellet with a fixed length, so as to prepare the obstruction explosion-proof material which is cheap in price, easy to process and excellent in performances.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of a polyolefin polymer barrier explosion-proof material. Background technique [0002] Inflammable, explosive and dangerous chemicals such as fuel are extremely vulnerable to combustion and explosion caused by external energy such as static electricity, gunshots, and collisions during storage, transportation and use, resulting in chemical plants, oil refineries, gas stations, automobiles, oil trucks, oil depots, Oil storage tanks and other accidents caused explosions, which caused irreparable huge losses to the property of the country and the people. For this reason, various countries in the world have successively developed various explosion-suppressing materials. In recent years, in the storage and transportation of flammable and explosive dangerous chemicals, a safety technology for preventing explosions is vigorously promoted, whic...
